One thing I find interesting in the analysis is the claim that crypto-currencies do not have effective short selling opportunities requiring a "long only" strategy. That is interesting as it seems like one of the few contracts that Etherium should provide, if one trusted any particular "stablecoin". Furthermore, it does seem that Binance (and probably others) do allow some shorting opportunities.
